Related Informational APARs: All Products . II04480 - DFP - PDSE Related Items ************************************************************ . IBM STATUS AND DIRECTION ======================== . DFHSM Datamover was introduced with DFHSM 2.5.0 and DFDSS 2.5.0. The original intent was to allow additional data sets to be system-managed. . DFDSS was unknowingly processing invalid ISV data: . ISV (Independent Software Vendors) do not always follow standard access method rules when developing applications. Since DFHSM is automated, and selects all data sets on each volume for processing, ISV data was being processed unknowningly. Even if vendors had a "warning" against moving their data in their publications, there was no way to notify DFHSM directly. . . Successful Backup/Migrate did not guarantee return: . Because DFDSS processes data sets using TRACK I/O, it did not detect any access-violations when backing up or migrating invalid ISV data. Such violations include: invalid PDS directory structures, embedded end-of-file marks, invalid VSAM index structures, and inappropriate DSORG values. . . As a temporary measure, IBM produced some PTF's that provided additional granularity of support. This support is provided via new keyword parameters on the SETSYS DATAMOVER command. . 1) Customers can select which data to process 2) MIGRATE and BACKUP selections can be different . . REVISED IBM STRATEGY ==================== . By August 1992, IBM management and technical support determined a revised strategy for DFHSM 2.6.0/DFDSS 2.5.0 and for the new DFSMS/MVS 1.1.0 product that focuses on the customer's need for both function and quality. Each is discussed below: . DFSMS/MVS 1.1.0 --------------- . The Strategy for DFSMS/MVS 1.1.0 involves the following: . 1) DFSMShsm will use BSAM, QSAM and IDCAMS access methods for the migration and backup of certain dataset types, including: ICF catalogs, PDS, SUL, uncataloged, cataloged in CVOL, and unmovable data. These will be documented in the DFSMShsm Implementation and Customization Guide. 2) DFSMShsm will use DFSMSdss for migration and backup of all other user data. 3) DFSMShsm will simplify SETSYS DATAMOVER by eliminating the need to select a method to use. . This allows IBM to re-engineer code to improve quality to the customer. . You may process PDS data sets with DFSMSdss via Batch or API. See the RFA Announcement Letter on additional considerations for the DFSMS/MVS 1.1.0 product. . . DFHSM 2.6.0/DFDSS 2.5.0 ----------------------- Current Status 01/05/93 ----------------------- . IBM's evaluation testing is complete. IBM has a high level of confidence that you can MIGRATE and BACKUP all data safely, provided the following: . 1) All closed maintenance identified in this Informational APAR is installed. 2) All open maintenance identified on this Informational APAR is evaluated to determine the impact to your installation. 3) Evaluate each ISV application for exceptions (data that should not be migrated) . If you have ISV (Independent Software Vendor) applications, contact each vendor to ensure that standard access methods are used. If standard access methods are not used, you can restrict migration for these data sets as follows: . System-Managed: Assign a Management Class with Attribute of NONE for "Command or Auto Migrate" . Un-Managed: Use the DFHSM SETMIG command with the NOMIGRATION parameter . . DFHSM supports the following data set types using DFDSS as its data mover method: . 1) All Physical Sequential, single volume and SMS-only multi-volume. 2) Direct Access (BDAM) 3) Empty VSAM data sets (HIGH-USED-RBA is ZERO) 4) PDSE (Partioned Data Set/Extended) 5) Long-Record VSAM (LRECL>32K) . DFHSM will use BSAM access methods only to process PDS data sets. DFDSS will not be used even if the SETSYS DATAMOVER options request it. . VSAM data sets not listed above are considered "Exportable". DFHSM will use IDCAMS access methods only to process Exportable VSAM data sets. DFDSS will not be used even if the SETSYS DATAMOVER options request it. . It is IBM's intent to re-investigate the Permanent Restriction closure of APAR OY57276. Any changes for support in this area will be reflected in this informational APAR. . COMMUNICATION OF STATUS ======================= All problems known to IBM that affect this support will be reflected in this Informational APAR. . It is IBM's intent to communicate our status more regularly via this Informational APAR, as well as traditional communication such as WSC FLASH and DFSMS Newsletter. .
